1、检查所需要的文件集
Powerpath4.3以上要求devices.pci.df1000f7.com 5.1.0.58以上，devices.fcp.disk.rte 5.2.0.17以上
检查文件集
# lslpp -l devices.pci.df1000f7.com devices.fcp.disk.rte
Fileset Level State Description
----------------------------------------------------------------------------
Path: /usr/lib/objrepos
devices.fcp.disk.rte 5.2.0.60 APPLIED FC SCSI CD-ROM, Disk,
Read/Write Optical Device

devices.pci.df1000f7.com 5.2.0.60 APPLIED Common PCI FC Adapter Device
Software
对应的补丁要求（仅仅针对5.2版本）
#instfix -a -ivk IY60183
IY60183 Abstract: Open failure on ESS with FC df1000fa adapter
IY60183 Symptom Text:

----------------------------
Fileset devices.pci.df1000f7.com:5.2.0.43 is applied on the system.
All filesets for IY62117 were found.
2、安装agent，先解压agent软件
注意：Agent的软件要求版本最好与存储本身的软件版本一致。
#unzip AIX_NAVIAGNTCLI_619.zip
进去到解压后的目录
# cd AIX_NAVIAGNTCLI_619
运行
#smit install_latest
安装目录选择[.]，表示本目录
软件列表选择需要安装的naviagent，或者是默认全部（因为本目录下只有agent）
> NAVIAGENT ALL
+ 6.19.0.4 Navisphere Disk Array Management Tool (AGENT)
> NAVICLI ALL
+ 6.19.0.4 Navisphere Disk Array Management Tool (CLI)
选择接受许可协议
ACCEPT new license agreements? Yes
回车安装
如果安装成功，将会自动在/etc/inittab中增加
naviagent:2:wait:/etc/rc.agent > /dev/console 2>&1
安装完成后，在启动之前，还需要配置agent
#vi /etc/Navisphere/agent.config
在如下部分增加：
user root # only on this machine
#user sblue@picasso # individual user "sblue" on host "picasso"
#user lgreen@hannibal # individual user "lgreen" on host "hannibal"
user system@192.168.168.190
user system@192.168.168.191
红色部分为需要增加的部分
3、安装powerpath ODM补丁
# zcat EMC.AIX.5.2.0.3.tar.Z| tar -xvf -
x ./README.5203, 21598 bytes, 43 media blocks.
x ./EMC.AIX.5.2.0.3, 15360000 bytes, 30000 media blocks.
#smit install_latest
选择安装软件列表或者是全部（假定本目录下只有该补丁）
> EMC ALL
+ 5.2.0.3 EMC CLARiiON Fibre Channel Support Software
+ 5.2.0.3 EMC CLARiiON HA Concurrent Support
+ 5.2.0.3 EMC Symmetrix AIX Support Software
+ 5.2.0.3 EMC Symmetrix Fibre Channel MPIO Support Software
+ 5.2.0.3 EMC Symmetrix Fibre Channel Support Software
+ 5.2.0.3 EMC Symmetrix HA Concurrent Support
如果在Symmetrix或者是CLARiiON不足的环境，可能会包安装错误，根据实际环境决定这个错误是否有影响，如有Symmetrix，CLARiiON的安装则会报错，反之一样。
如果在非ha的环境下，EMC.Symmetrix.ha.rte与EMC.CLARiiON.ha.rte也可能会出现安装错误，如果是非ha就没有关系的了。
如一般在单机情况下使用Clariion存储，如cx700,cx3-80等等，只需要安装第一个文件集即可。
4、安装powerpath
#gunzip EMCpower.AIX.4.5.1.tar.gz
# tar xvf EMCpower.AIX.4.5.1.tar
x EMCpower_install, 9830400 bytes, 19200 media blocks.
#smit install_latest
安装目录选择本目录
软件列表选择Powerpath或者是全部（本目录下只有powerpath）
>EMCpower ALL
+ 4.5.1.0 PowerPath Base Driver and Utilities
+ 4.5.1.0 PowerPath Consistency Group Extension and Utilities
+ 4.5.1.0 PowerPath HighRoad Extension and Utilities
+ 4.5.1.0 PowerPath Multi_Pathing Extension and Utilities
+ 4.5.1.0 PowerPath Multi_Pathing Extension for Active Active
+ 4.5.1.0 PowerPath Multi_Pathing Extension for Active Passive
+ 4.5.1.0 PowerPath Multi_Pathing Extension for Clariion
回车，接受协议，开始安装。
安装完成后，在/etc/inittab中，会增加一行
rcemcpower:2:wait:/etc/rc.emcpower set_ipldevice > /dev/console 2>&1
安装之后，需要输入序列号
#emcpreg -install 输入powerpath序列号
以下是powerpath的管理命令
# powercf -q
#powermt config 产生Emcpower设备
#powermt display dev=all 查看所有Emcpower设备及状态
#powermt display paths 查看光纤卡到EMC的路径
注意：先安装odm补丁，再安装powerpath，安装完成后需要重新启动一下。
安装过的补丁与powerpath可以通过如下命令查看
# lslpp -l EMC*

5、卸载powerpath
注意，确保先停止agent
# /etc/rc.agent stop
删除powerpath盘
#powermt remove dev=all
删除所有hdiskpower*与hdisk*，如
删除EMC的hdiskpower[x]
#lsdev -Ctpower -cdisk -F name | xargs -n1 rmdev -dl
#rmdev -dl powerpath0
#删除EMC CLAR硬盘
#lsdev -CtCLAR* -F name | xargs -n1 rmdev -dl
卸载软件
# smit remove
在SOFTWARE name上，用F4或者Esc+4打开列表
AIX-rpm-5.2.0.50-1
EMC.CLARiiON.fcp.rte
EMC.Symmetrix.aix.rte
> EMCpower.base
> EMCpower.consistency_grp
> EMCpower.hr
> EMCpower.multi_path
> EMCpower.multi_path_aa
> EMCpower.multi_path_ap
> EMCpower.multi_path_clariion
并用F7或者Esc+7多选，选中EMCpower的部分，就是powerpath的安装软件包。
在如下选项中
PREVIEW only? (remove operation will NOT occur) no
REMOVE dependent software? no
EXTEND file systems if space needed? no
DETAILED output? no
确认不是仅仅是review，REMOVE dependent software一般采用默认值no即可，如果确认需要，可以采用yes来删除依赖的相关软件。
回车执行完后，powerpath就卸载删除了。
6、故障处理
在一些老的powerpath版本如4.2上面，如果hdiskpower出现混乱，如pvid的混乱或者是minor does not match with the hdiskpower number这样的事情，如
#ls -Ralsi dev|pg|grep hdiskpower
4258 0 brw------- 1 root system 47, 12 Mar 28 14:48 hdiskpower0 4392 0 brw------- 1 root system 47, 13 Mar 28 14:48 hdiskpower1 4394 0 brw------- 1 root system 47, 14 Mar 28 14:48 hdiskpower2
可以采用如下方法重新做
vary off volume groups on SAN (if any):
- for i in $(lsdev -Cc disk | grep hdiskpower | awk '{print $1}')
- do
- odmdelete -q name=$i -o CuAt
- odmdelete -q name=$i -o CuDv
- odmdelete -q value3=$i -o CuDvDr
- done
#odmdelete -q name=powerpath0 -o CuDv
#odmdelete -q name=powerpath0 -o CuAt
#rm /dev/powerpath0
这里移除老的powermtpath软件
#cd /dev; rm hdiskpower*; rm rhdiskpower*
#savebase -v
#reboot
这里再安装新的powerpath软件，并重新配置
# powermt config
或者
vary off volume groups on SAN (if any):
#cd /dev
#echo hdiskpower* | xargs -n1 rmdev -dl
# rmdev -dl powerpath0
每一个光纤卡执行
#rmdev -Rdl fcs(x)
执行cfgmgr与emc_cfgmgr
最后执行
#powermt config
